Application filed October 11, 1922. Serial No. 593,876.

To. all whom it may concern:

Be it known that I, ELMER R. Porn, a citizen of the United States,residing at Hamilton, in the county of Essex and State of lviiassachusetts, have invented certain Improvements in Nailing Machines,of which the following description, in connection with the accompanyingdrawings, is a speciiication, like reference characters on the drawingsindicating like parts in the several figures.

This invention. relates to nailing machines, and especially to those forattaching heels to shoes. It more particularly concerns itself with thesupplying in such machines of the nails to be driven.

In heeling shoes, the practice heretofore has been to deliver nails tothe die-block of the heeler by a loader, into which said nails wereeither fed manually by the operatorsassistant, or supplied automaticallyby nail-distributing mechanism. An organization of the character firstindicated is illustrated in Patent No. M0885, Pope, February 24, 1891,while that last mentioned is shown in Patent No. 1,005,803, Pope,Uctober 10, 1911 taken in connection with No. 1,157,688, Glidden,October 26, 1915. Under the first method, the operator tends to attachthe heels more quickly than one assistant can supply the nails for them,thus placing a drag upon the work. If two assistants are employed, as isprovided for in Patent No. 1,005,303, the expense is, of course,considerably increased. Automatic nail-feeding requires the use ofmechanisms relatively costly to construct and maintain. My invention,keeping the simplicity of hand feeding, provides, as an object, for areserve supply of nails, which may be built up at such time astheactivities of the operator are reduced, and drawn upon when theassistant might otherwise fall behind. To accomplish this, the nails areheld in series in passages in a magazine, to be successively deliveredone by one from each pa sage by controlling means, with which isassociated means for retaining the succeeding nails of a series duringthe feed of the terminal nail. Since the nailing design, that is, thepoints at which the nails are insorted in the heels, changes frequently,according to the size or style of shoe operated upon, themagazine-passages are arranged in sets in accordance with the variousdesigns to be employed, and I furnish means for permitting the deliveryof the nails from any one of the sets while the other sets remainineffective. This control may be exercised at both extremities of thepassages, allowing for preventing both the introduction of nails to andtheir delivery from the passages. With the controlling means isassociated means for determining its position, and consequently theparticular set of passages which shall be in use, and I guard againstinterference with the positioning of the controlling means by the nails,as by causing this position-determining means to control the movement ofthe nails in the magazine, preferably by contact with them.

One of the various embodiments which my invention may assume is shown inthe accompanying drawings,

Fig. 1 being a front elevation of a portion of a nailing machine towhich my invention is applied;

Fig. 2, a top plan view of the nail-holding magazine;

Fig. 3, a vertical section on the line 3-3 of Fig. 2;

Fig. i, a similar view on the line 4-4l of Fig. 2; and

Fig. 5, a sectional detail on the line 5-5 of Fig. 2.

At 10 appears the frame of a heel-attaching machine, upon which issupported a dieblock 12, preferably having multiple sets ofnail-receiving openings, each set corresponding to the design which thenailing is to assume for a particular size and form of heel to beattached. Operating in these openings are drivers 14 depending from atop girth l6 bridging the reciprocat-ory side rods of the machine, oneof which rods is shown at 18. Surrounding the side rod, to swing from anail-delivering position over the dieblock-openings to a nail-receivingposition at one side of the. machine, is a loaderarm 20, carrying atitsouter extremity a loader-block 22. This block has in it multiple setsof openings, controlled by a nailsupporting shutter 23 and arrangedsimilarly to those in the die-block, it serving to carry loads of nailsto said die-block for the heel-attaching operation.

Fixed upon the frame of the machine, adjacent to the point at which theloader-arm 20 is mounted, is a bracket 24, which carries base 30 and theblock-section 36. i this plate normally in its nail-supporting a stop 26limiting the outward movement of the loader-arm, and a latch 28, bywhich said loader-arm may be temporarily retained in its nail-receivingposition. Secured to the upper "face of the bracket is the base-section30 ot a nail-magazine, and rising from this base are studs 32, shown asthree in number, holding at their upper ends a top plate 3%. Between thebase and top plate, positioned by the studs, is a block Consisting of alower section 36 and an upper section 88 furnishing the body of thenail-magazine. Extending in a substantiall'y vertical direction throughthe block-sections are nail-holding passages to, these, like those ofthe loader-block and die-block, being arranged in multiple setscomprehending all the nailing designs. Openings tl in the top plate andbase are alined with these passages to allow the introduction anddelivery of the contained nails.

The lower'ext'remities of the passages 40 are normally closed by a plate42 mounted to slide at the bottom of a space between the To holdposition, with its iinperforate portions in alinement with the passages40, a spring at, situated in a recess in the base, exerts its force uponthe plate through a pin 4:5 projecting downwardly from the latter. Thenthe passages in the magazine are thus closed, the'nails i'neach arearranged in a continuous series, the lowest resting with one e tremityupon the plate, while each succeeding nail is supported by that beneathit, the

transverse dimensions of the passages being such that but a single nailat a time can travel'through any portion. The height of the passages issuflicient to allow a substantial number of nails to be maintained ineach series, which, as shown in the drawing, for the particular size ofnail illustrated, consists 01 four. Adjacent to the imperforatenail-supporting portions of the plate 42 areopenings 4:8, which, uponmovement of the plate against the spring 44, may be brought opposite thelower extremities of all the passages, thus freeing these for thejdelivery of the terminal nails. As is best shown in F1g. 2 of thedrawings, these open ings need notbe individual to the passages,

but may in some instances be enlarged to correspond to a group of these.lVith the succeeding nails of the series co-operates a member consistingof an L-shaped support- "ing plate and a contact-plate 49 carried on theupper face of the plate 50, both beingarranged to slide between thesections 36 and 38 of the magazine-block. In the plate 50 is a slotreceiving a pin 51 depending from the companion plate, and between thepin andan extremity of the slot is a spring '53, acting to force thecontact-plate to the left, as viewed in Fig. 1 of the drawings.

Through the plate 49 are openings corresponding in number and form tothe openings as, but not having the same positions transversely of thepassages. The relation of the openings 52 and =18 is such that when theplate 42 is moved to tree the ends of the passages, the edges of theopenings 32 in the contact-plate bear against the side of the nails nextto those to be deliveredto clamp them yieldably, and hold them and thosewhich they support against downward displacement. lVith the plate L2 inits nailretaining position, the openings 52 of the plate l9 move intoalinement with the passages lO, so that they no longer act upon thenails. The plates 42 and 50 are preferably connected to move together,there being shown for this purpose bolts 54, 5a, which secure them tothe upper and lower races oi a spacing block 56. Consequently, thecontact-plate l9 is under the normal positioning influence of the springat. The movement of the plates is under the control of the loader-arm20, this having an upward projection (50 arranged to contact with aninclined or cam-surface 62 upon the outer edge of the plate 12. With theloader-arm in any position other than that in which it is latched by thedevice 28, the projection is out of contact with the can'i-surl'ace 62.At this time the spring ellholds the plate a2 in its nail-retainingposition, and the plates 50 and l9 with the openings 52 substantiallycoinciding with the passages. \Vhen, however, the loader-arm is swungback fully to its nail-receiving position and latched, the projection(30 rides over the surface 62, forcing the plates 4-2, fit) and 49 tothe left, as viewed in Figs. 2 and 3 of the drawings, causing thefirst-mentioned plate to open the passages and the plate 4-9 to bearagainst and hold the succeeding nails, so that the terminal nails onlytall from the magazine into the loader-blockopenings ready for deliveryto the dieblock.

To render a particular set of passages eiiective, so that in themovement of the plates by the loader-arm the nails delivered from themagazine to the loader block shall be arranged in accordance with thedesign in which they are to be placed in the heel of the shoe operatedupon, there is associated with the magazine controlling means, hereshown as including two plates or disks 64L and 66, which arerespectively located between the section 36 of the magazine and the baseand between the section 38 of said magazine and the top plate. The disksare fixed upon a spindle (i8 journaled vertically in themagazine-sections, and contain vertically alined openings 70. Theseopenings, like those in the die-block, loaderblock and magazine, includesets for all the nailing designs, and are so arranged that by rotatingthe disks to different angles, one or another of the sets may be causedto coincide with the passages in the magazine, at which time all theother sets of passages are closed. Different settings of the diskprovide for the rendering effective of all the sets ofmagazine-passages.

To permit the selection and temporary retention of the design which isto be utilized for any heel operated upon, the periphery of ti e plate64 has, at 72, a series of recesses, each recess corresponding to one ofthe set tings of the magazine, and having, if desired, inscribed uponthe upper surface of the plate adjacent to it an identifying designationfor this design. With these recesses 72 co-operates aposition-determining mem ber 74, mounted to slide between the disk 64and the magazine-section 36 and having a projection 76 so formed that itwill enter any one of the recesses brought into registration with it andhold the selected setting of the controlling disks. The portion of themember 74 lying between the disk and magazine-section has movable withit, arranged to yield against a spring 80, an auxiliary plate 77, actingsimilarly to the contact-plate 49 and having openings 7 8 co-opcratingwith the passages 40. When the projection 76 lies Within one of thedisk-recesses, these openings are opposite the passages, leaving thesefree for the movement of the nails. When the projection is drawn out ofthe recess which it may occupy, the edges of the openings Y8 are broughtinto contact with the terminal nails in the passages, clamping these andthe nails which they support against downward movement, and thuspreventing their interference with the setting of the disk by enteringits openings. It is to be noted that this interference would not becaused by nails in the passages which are in use, since here the lowestnails have been delivered, and those succeeding them retained by theplate 49. Lhere may, however, be idle series in the unused pa"- sages ofother sets, which would fall into the disk-openings were precautions nottaken to avoid this. To allow for the convenient setting of the disksand the nail-retaining action justv described, there is mounted,adjacent to the member 74, to slide upon the base 30, a latch 82arranged to enter a recess 84 in the member 74, this engagement takingplace when the projection 76 is withdrawn from the disk-recesses 72. Aspring 86 acts upon the latch 82 to force it toward the recess 84 whichit is to enter. To free the member 74 to permit it to be moved to itsinmost setting-retaining position, a finger-piece 88 appears rising fromthe latch, by which it may be drawn out of the recess 84.

In using the apparatus, let it be assumed that the disks 64 and 66 havebeen set for some particular nailing design which has beenin use, andthat there are nails N within the magazine-passages 40. The operator,now desiring to use another nailing design, draws out the member 74until it is latched at 82. At this time, the projection 76 has freed thedisk 64, and the edges of the open ings 78 in the member 74 are holdingany nails which may be contained in previously unused sets of passagesthat they are resting upon the disk. The operator now turns this 6. s tothe desired angular position, shown by the marking associated with therecesses 72, and draws back the latch by its finger-piece 88 to allowthe position-determining projed tion to enter the recess which isopposite it. This movement of the member 74 not only locks the disk forthe new design, but also releases all the nails which it may have beenengaging. \Vith the loader-arm away from the latch 28, the lowerextremities of the selected set of passages are closed by the plate 42.Consequently, the operators assistant, at any time free from otherduties, may supply nails to the magazine-passages through the openings41 in the top plate and in the disk 66, the other passages than those ofthe set selected being closed by the imperforate portions of the plate.When a load of nails is to be delivered to the die-bl0ck, the operatorsassistant swings the loaderarm to its extreme outward position againstthe stop 26, and when it is engaged by the latch 28, its projection 60,acting against the surface 62, cams over the plates 42, and 49. Theformer frees the lower ends of the magazine-passages which have beenleft open by the setting of the disk 64, allowing this set of nails todrop into the openings in the loader-block. Coincidentally with this,the contact-plate 49, by its engagement with the succeeding nails of theset, holds the remainder of the series against downward travel. Havingthus supplied the loaderblock with nails, the assistant carries it overthe die-block, intothe openings of which the nails are deposited. Assoon as the projection of the loader-arm leaves the surface 62, theplate 42 closes the passages in use, while the plate 49 frees them forthe descent of the remainder of the nails. If the nail-supplying laborof the assistant is interfered with, he still has a reserve of threenails for the entire set to draw upon, so that this number of heels maybe attached before any more nails are introduced into the magazine. Onthe other hand, if he has, at times, an opportunity to supply more thanthe one set of nails, he may do so up to the capacity of the magazine.
